Today we’re discussing whether the CheckRa1n Jailbreak can be updated to support A12 and A13 devices in any way. The A13 and A12 devices, are iPhone XS, iPhone XS Max, iPhone XR, and iPhone 11 / SE 2020. By default CheckRa1n only supports iPhone X and lower (A11 and lower), so would it be to somehow update CheckRa1n in the future to work with the rest of the devices as well? Maybe!
You see, CheckRa1n Jailbreak is built on top of CheckM8, a very powerful bootrom exploit that cannot be patched by Apple that was released by developer @axi0mX. While the memory leak has been patched by Apple on A12, the UaF was not, thus leaving a small possibility for CheckRa1n.
